  • Multiple specialty or narrowcast channels can be added to the viewing experience, creating a highly personalized information set, and further increasing the opportunities for revenue generation and promotion.
  • While a clearly advantageous aspect of the current invention is to synchronize new media such as web content to traditional broadcasting such as television or radio, it is within the anticipated scope of this invention to permit multiple synchronizations between many types of time based and static media and devices such as broadcast television or radio, multimedia files, audio files, pictures, web pages, computer games, PDAs, mobile phones, musical instruments, and specialized databases.
  • the present invention provides network operators, content providers and independent developers with the integrated content publishing software environment to rapidly transform standard web-based content into media rich, dynamic, broadcast ready interactive applications.
  • the system and software combines the latest iTV technology with standard internet protocols, for example XML and HTTP, to create compelling interactive applications, built for multi viewport interactive television.
  • the present invention includes a server and runtime architecture to provide the benefits of XML authoring while delivering efficient, flexible and robust multi viewport interactive applications.
  • the present invention provides network based applications that in conjunction with standard software such as web browsers and networked server computers, support automatic, dynamic content updates, such that the information displayed on a viewer's computer screen is always up-to-date.

  • the present invention is adapted to quickly access the application pages retrieving the latest data available.
  • This data may be an enhanced television application, accessed through a virtual channel, or from some other data source.
  • the present invention provides an option to create static broadcast files ready to broadcast through the system or other server systems. While the benefits of dynamic content updates are reduced when using static broadcast files, the operating requirements are simplified, allowing a more cost effective deployment of a large number of applications.
  • the system is adapted to interface seamlessly with either a suitable system projector or an embedded solution HTTP extension, to provide a complete HTTP-based environment for handling transactions over the return path.
  • a suitable system projector or an embedded solution HTTP extension to provide a complete HTTP-based environment for handling transactions over the return path.
  • This enables a wide range of transactional iTV applications, including voting during a television program, ordering a catalogue during an enhanced television advertisement and buying goods and services from a shopping channel.
  • the present invention saves time and effort over conventional systems.
  • Applications consist of pages built using presentation templates defined in XML by application designers. Graphic designers, using standard graphic design tools, may easily create media assets that are then easily linked into applications, ready for broadcast. Data and presentation are clearly separated for easy application maintenance and simplified integration with existing data sources. The data elements and the presentation templates are merged using standard web dynamic page building tools. Built-in text formatting features allow authoring features for international character sets. To provide maximum flexibility, developers may also use the proprietary scripting language to develop new productions that can be reused across the system
  • Deploying iTV applications in combination with the present invention provides additional cost savings. Integration with a screen interactive runtime application may be done once for all proprietary system based applications deployed on a network, which simplifies the application-testing phase. Integration with content sources and transaction servers relies on standard protocols, allowing for fast and reliable implementation. It is also contemplated to provide a broadcast version for network operators which also includes an unlimited development environment.

  • relevant web URL's for example, show-related trivia and other information, searches, and advertising
  • the end user or viewer downloads a zero- install, small-client player, for example called the "Projector,” which receives URL data from a remote server running the platform's broadcaster software and points an end user's web browser to the specified web pages.
  • Viewers may choose from two broadcast "modes,” designed to support live broadcast programming and VOD/PVR programming respectively.
  • the platform allows producers to download and cache multimedia content including graphics and text from web pages to viewers' computers before they are displayed.
  • the system employs a tool, for example called a "Switch,” that allows producers to 1 ) enter the URL's they wish to use into fields in the sequence in which they will be delivered to viewers' computers, and 2) schedule the times at which those URL's will be automatically delivered.
  • a tool for example called a "Switch”
  • producers can trigger the delivery of each URL manually.
  • the Projector player may also include a scoreboard-style message window that allows broadcasters to give live text updates with minimal delay time.
  • a primary aspect is to develop a simulcast internet media distribution system that could broadcast supplementary web pages and video pages in synchronization with a regular television or radio broadcast or other primary media channel content, and preferably the distribution mechanism stays in synchronization within one second over a period of one hour.
  • a first limitation is the inability to have constant synchronization between the television broadcast signal and the new media signal. These two signals are distributed through two entirely different communication networks.
  • the television signal is distributed through the television station's master control and the media signal is broadcast through the internet. It was found that the streaming mechanisms used to distribute simulcast media to the client suffered from unacceptable drift. Similar limitations apply with respect to radio broadcasting. As the simulcast media needed to stay in synchronization within one second or so, the buffering and drift inherent in these existing internet streaming technologies needs to be overcome.

  • Other issues arose with the end user or viewer when receiving information from the server to display video or pictures in synchronization with the television or radio broadcast or other primary media channel content. It was found that internet latencies were preventing clients from getting the desired content in time. To try and overcome the problems with the latency, it was found that by using, in combination with new techniques of data based pointers, cues from a server, the present system allowed for several systems to be synchronized together.
  • a further advantageous aspect of the current invention is that it does not require a broadcast communication channel from the primary server to the end- user's computer.
